"TalkTalk has complied with the Court Order and blocked access to The Pirate Bay as instructed," a company spokesperson said.

The embargo comes mere days after O2 and its subsidiary, Be Broadband, also reluctantly cut off access to the domain. The list of service providers preventing access to Pirate Bay, as dictated by the court order, is now complete except for BT - who has been granted more time to comply.

Sky Broadband, Everything Everywhere, and Virgin Media were the first to implement the blockade, which was the result of a long running legal battle instigated by the BPI - the trade organisation that represents Britain's recorded music business.

In April, the High Court in London agreed with the BPI's claim that the service provided by The Pirate Bay - which provides magnet links to file downloads - infringed the copyright of recording artists.

Critics argue that the blocks are ultimately futile, as a number of means to circumvent them, including the use of virtual private networks and proxy servers, are readily available.
